iatented Apr. 6, 1937 PATENT OFFICE CARDBOARD BOX John C. Krudener, Clifiside Park, N. J., assignor to Continental Folding Paper Box 00., Inc., Ridgefield, N. J., a corporation of New York Application July 21, 1936, Serial No. 91,701

7 Claims. (Cl. 40-126) This invention relates to cardboard boxes or the like and is particularly directed to cardboard dmnmies.

In displaying packaged goods in store windows, show cases and such places, it is the practice to employ dummy packages rather than to use the packaged goods. The advantages of such practice is well known and can readily be appreciated.

It is a desideratum in such practice to provide dummies which simulate the packaged articles, consequently many attempts have been made to provide dummies which are substantially perfect similations.- V

In ordinary cardboard boxed articles the empty cardboard boxes may be employed for display purposes with entire satisfaction. However, where odd shaped boxes, tins and the like are employed considerable difiiculty has been experienced in making dummies of cardboard which are indistinguishable from the originals.

As an illustration, a tobacco can has fiat ends and curved sides. Dummies of such cans or tins have heretofore been made of non-metallic material but it has been found that the ends do not give the appearance of being flat due to the employment of flaps, tabs and the like to hold the dummy in assembled or set-up position. Also, in such dummies it has been necessary to provide longitudinal scores in the sides of the dummy in order to simulate rounded or curved sides, Which scoring is readily detected and the perfection of the simulation fails.

It is an object of the present invention to provide a dummy which will be a perfect simulation of flat tin containers, for example, having flat ends, free of any flaps or tabs, and curved sides free of scoring.

Another object of the present invention is the provision of a device of the character indicated wherein the curved sides are frictionally held in curved position without gluing and without the necessity of tabs or flaps.

Other objects of the present invention will be apparent from. the following description and the accompanying drawing, inwhich drawing:

Fig. 1 is a plan View of the blank from which the article is made;

Fig. 2 is a perspective view of the same blank after the first folding and gluing;

Fig. 3 is a perspective view of the completed article;

Fig. 4 is a sectional view on line 44 of Fig. 3; and

Fig. 5 is a sectional view on line 55 of Fig. 3.

Referring to the drawing in detail, the blank from which the set-up dummy is formed comprises a central or body portion I which eventually is to form the front wall of the article. This central portion is provided-with integral extensions -3 and 5 extending longitudinally therefrom and a member 1 comprising a brace or strap 9, end member II and a flap I3 extending laterally thereof. On the side or end of the central or body portion I opposite the member I there is another end flap I5 to which the flap I3 is to be secured by means of adhesive I! when the article is set up.

The blank is scored at I9 and 2| along the line of juncture of the central or body portion I and the end members I I and I5, respectively, whereby the end members may be readily'bent or folded at right angles to the portion I when the blank is connected into a dummy. The brace member I is also scored at 23 to facilitate bending or folding along the line of juncture of the same to the endmember II and also at 25 whereby the flap I3 may be bent or folded under the end flap I 5 to be secured thereto.

Each of the extensions 3 and 5 of the body portion I is provided with a pair of lateral projections 21 and 29, respectively, the purpose of which will be appreciated from the following description.

Articles of the character indicated are prefer:- ably shipped fiat for economy of space. The article of the present invention is adapted to be shipped in the flat condition illustrated in Fig. 2.

In this figure the member I has been folded along the scoring 23 and the end member I5 folded along the scoring I9 over upon the flap I3 and secured thereto by means of the adhesive II.

In cuttingthe blank illustrated in Fig. 1, I lay the material so that the grain extends transversely of the body member I or longitudinally of the completed article, as I have found that the material when rolled with the grain will not crack but will readily roll in curved formation.

When it is desired to convert or fold the blank illustrated in Fig. 2 into a dummy as illustrated in Fig. 3 the brace member 1 is raised and the extensions 3 and 5 of the body member rolled under the brace in overlapping relation, as seen in Fig. 4. Inasmuch as the grain of the paper or cardboard extends transversely of the body member and hence of the extensions 3 and 5 or longitudinally of the rounded or curved ends 3| and 32 produced by rolling the extensions under the brace l, the material may readily be rolled without cracking and without the necessity of scoring.

The ends of the extensions 3 and 5 are overlapped under the brace or strap 1. The resil- 5 iency or the tension of these overlapped members tends to hold the brace away from the front wall. The overlapping of these members and the resiliency of the same and the pressure exerted against the brace member serves to frictionally hold the side members in rounded or curved formation.

The projections 21 and 29 are of a width equal to the width of the curved ends 3| and 32 and in effect these ends are slightly increased in length to the extent of the depth of the projections 2! and 29. The projecting portions 21 and 29 of the members 3 and 5 about the curved ends of the end members II and I5 serve to limit the inward movement of these members.

It will be appreciated that the article of the present invention will simulate the usual parallelogrammic tin or can having its front wall unobstructed and well adapted for the the usual printed matter, the back of the article which consists of the brace or strap 9 likewise being fiat, the ends of the article are flat and the article as a whole is free of any visible flaps, tabs, seams, scoring or the like.

It is to be understood that various changes 3 and modifications may be made in the article herein illustrated and described without departing from the spirit and scope of my invention.

What I claim is:

35 1. An article of the class described, comprising a front wall, a rear wall, end walls securing said front wall and rear wall to each other and having curved ends, side members integral with said front wall and rolled under said rear wall into engagement with the curved ends of said end walls, said members being of such lengths as to be overlapped beneath said rear wall whereby frictionally to be held therein to provide rounded or curved side walls.-

2. An article of the class described, comprising a front wall, a rear wall, side members integral with said front wall and inserted between said walls and frictionally held therein to provide rounded or curved side walls, and projections on said side members to limit the depth of insertion.

3. An article of the class described, comprising a single sheet of material adapted to be formed into a box having afront wall, flat end walls, a brace connecting said end walls and constituting the rear wall, side members integral with said front wall and rolled under said brace frictionally to be held therein to provide rounded or curved side walls and to retain said walls separated.

4. An article of the class described, comprising a single sheet of material formed into a box having a front wall, a rear wall, side members integral with one of said Walls and inserted between said walls to retain said walls in spaced relation, said members being of such lengths as to overlap within said walls whereby to be held therein to provide rounded or curved side walls, and projections on said side walls to limit the depth of insertion.

5. An article of the class described, comprising a front wall, a rear panel, fiat end walls secured to each other by said panel, members integral with said front wall and having portions rolled under said panel, said portions being of such length as frictionally to be held therein, the portions of said members not overlapped constituting rounded or curved side walls.

6. An article of the class described, comprising a sheet of flexible material having a body portion, side members integral therewith, laterally projecting portions integral with said body portion and scored at the line of juncture whereby the same may readily be bent at right angles thereto, one of said projecting portions being secured to the other of said portions to form a brace, said side members each having a pair of projections and being rolled with the grain of the material under said brace to a depth limited. by said projections to retain the said brace separated from said body portion and to provide rounded or curved side walls for the completed article.

7. An article of the class described, comprising a sheet of flexible material cut to form a central body member which is eventually to constitute the front wall of the completed article, integral portions which are eventually to constitute the side walls of the article, said portions being of such dimensions as to be overlapped in the completed article, lateral projecting members at opposite sides of said central body member, scoring along the line of juncture of each of said members to said central body member to facilitate the folding of said members at right angles thereto to constitute flat end walls of the completed article, a laterally extending portion which is eventually to constitute the rear wall of the completed article integral with one of said members, scoring along the line of juncture of said rear wall member to facilitate folding of the same and a flap at the extremity of said rear wall member secured to the flat end wall member at the opposite side of said central body portion, the portions constituting the side walls being rolled under said rear wall member in overlapping relation to retain said rear wall separated from said front wall and to provide rounded or curved side walls for the completed article.
